ADOLPHE KEGBESSE, OF TSARSKOYE SELO, RUSSIA.

MOTOR-SLEDGE.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed April 21, 1913. Serial No. 762,644.

To allwhom it may concern:

Be it known that I, Aoonrirn Kicmassn, a citizen of France, and residentof Tsarskoye Selo, Russia, have invented certain new and usefulImprovements in Motor-Sledges, of which the following is aspecification.

The proposed combination of a motor-car and a sledge offers thepossibility of progressing in any desired district as it allows tochange from wheels to'runners and vice versa. 1 I

The characteristic features of this invention reside in the employmentof rotary sledge runners whichare secured to the rotating endsofthe-front axle and in the driving mechanism which is connected with themotor of the vehicle and forms therewith the rear runners of the sledge.

The invention is shown in the accompanying drawing the figure of whichshows by way of example'the side elevation view of one form ofembodiment of the proposed motor sledge.

Secured to'the ends of the front axle l are two very large runners 2which are provided with openings adapted to let pass a part of the frontwheels; these runners are mounted in such a manner thatwhen the vehicletravels over solid ground (not covered with snow) they are a shortdistance above the ground and that when the vehicle encounters a snowcovered surface, the runners adjust themselves automatically on thissurface in such a manner that the motor car from progressing on thewheels starts progressing on the runner. These front run n r. beprovided with a device of adjusting their height above the ground so asto allow of their travel on various kinds of grounds. When the vehicleagain passes over to asnow free surface the runners areagain-liftectfrom the latter and the motor carcontinues traveling onthe'wheels.

The sledge isdriven by two endless belts 3 one ofwhiclr is provided oneach side and which passes over the .pulleys 4 mounted on the rear. partof the vehicle. Each pulley 4 is mountedon the end of a lever 5 so as tobe able to freely rotate thereon. Each lever fris-provided'with anintegral link (3, the upper ends of said links being pivoted to theendsof the leaf springs 7, mounted on the rear axle. The inner ends of thelevers 5 are provided with a guide-roller 9 which contributes insecuring the continuous tensioning of the lower half of the belt. Theouter ends of the levers 5 are pivotally supported on the shafts l, andconnecting the shafts is a horizontal bar 1. In this manner the fullelasticity of the system as well as the distribution of the load overthe whole length of the bell are ascertained. The rear pulley 4 isbesides surrounded by the transn'iission chain 10 which engages a wheelon the rear axle 8 of the motor car and imparts rotary motion to thesaid pulley 4. In this manner the belts 3 are continuously driven by theaction of the motor of the vehicle. This driving device occupies such aposition that it is adapted to travel both on solid ground and on layersof snow of different thickness.

Moving in one direction or the other under the action of the motor, thebelts cause the sledge to travel forward or backward and at the sametime keep the motor sledge on the surface of the snow.

Having now fully described my said invention, what I claim and desire tosecure by Letters Patent is:

1. In combination, a vehicle frame, an axle on the vehicle frame, leafsprings mounted on the axle, a system of levers supported by. the leafsprings, rollers mounted on the system of levers, traction belts passingaround certain of the rollers, and means operated from the axle torotate the rollers and move the traction belts.

2. In combination, a motor vehicle including a power driven shaft,longitudinal springs mounted on the shaft, arms having integralextensions, the latter pivoted to the ends of the longitudinal springs,rollers at the lower ends of the arms, a bar pivotally connected to theupper ends of adjacent arms, rollers mounted at the ends of the bar,traction belts engaging the last mentioned rollers, and means betweenthe power driven shaft and the last mentioned rollers for operating thebelts, the first mentioned rollers engaging the belts and holding the.latter in contact with the surface traveled on.

In, testimony whereof I have hereunto set my hand in presence of twowitnesses.
